  Aurones as histone deacetylase inhibitors: Identification of key features

  摘要：

  In this study, a total of 22 flavonoids were tested for their HDAC inhibitory activity using fluorimetric and BRET- based assays. Four aurones were found to be active in both assays and showed IC50 values below 20 mu M in the enzymatic assay. Molecular modelling revealed that the presence of hydroxyl groups was responsible for good compound orientation within the isoenzyme catalytic site and zinc chelation. (C) 2014 Elsevier Ltd.

• Synthesis of aurones under neutral conditions using a deep eutectic solvent
  作者：Ian Hawkins、Scott T. Handy

  DOI：10.1016/j.tet.2013.08.060

  日期：2013.11

  Of the various methods available for their synthesis, the simplest involves the condensation of a coumaranone with an aldehyde. This reaction can be performed under acidic or basic conditions. We have recently discovered an effectively neutral set of conditions that employ the deep eutectic solvent comprised of choline chloride and urea as both solvent and catalyst. Modest to good yields can be achieved

  Aurones是黄酮类天然产物家族中一个有趣但很少研究的成员。在可用于合成的各种方法中，最简单的方法涉及香豆素与醛的缩合。该反应可以在酸性或碱性条件下进行。最近，我们发现了一组有效的中性条件，它们采用由氯化胆碱和尿素组成的深共熔溶剂作为溶剂和催化剂。对于多种醛，可以实现中等至良好的产率，从而促进从生物学和光谱学角度对金刚烷的进一步研究。

  A Pd-catalyzed oxa-(4+4)-cycloaddition between 1-azadienes and (2-hydroxymethyl)allyl carbonates is described. Aurone-derived azadienes furnished polycyclic 1,5-oxazocines in good yields. Interestingly, linear azadienes have also been involved and yielded monocyclic heterocycles with complete regioselectivity. DFT calculations were carried out to gain insight on this observation.

  kinase-related apoptosis-inducing kinase-2 (DRAK2) is a serine/threonine kinase that plays a key role in a wide variety of cell death signaling pathways. Inhibition of DRAK2 was found to efficiently protect islet β-cells from apoptosis and hence DRAK2 inhibitors represent a promising therapeutic strategy for the treatment of diabetes. Only very few chemical entities targeting DRAK2 are currently known. We carried

  死亡相关的蛋白激酶相关的凋亡诱导激酶2（DRAK2）是一种丝氨酸/苏氨酸激酶，在多种细胞死亡信号传导途径中起关键作用。发现抑制DRAK2可有效保护胰岛β细胞免于凋亡，因此DRAK2抑制剂代表了治疗糖尿病的有前途的治疗策略。目前仅知道靶向DRAK2的化学实体很少。我们进行了高通量筛选，并将化合物4鉴定为中度DRAK2抑制剂，IC50值为3.15μM。随后对命中化合物4的SAR研究导致开发出新型的benzofuran-3（2H）-DRAK2抑制剂系列，具有针对26种所选激酶的增强的效能和有利的选择性。重要的是，大多数有效化合物40（IC50 = 0.33μM）和41（IC50 = 0。发现25μM）以剂量依赖性方式保护胰岛β细胞免于凋亡。这些数据支持以下观点：DRAK2的小分子抑制剂代表了治疗糖尿病的有前途的策略。

  An organocatalytic regioselective synthesis of aurones from o-alkynoylphenols was achieved. A catalytic amount of tributylphosphine selectively induced the 5-exo cyclization of o-alkynoylphenols under ambient conditions leading to aurone derivatives in high to excellent yields.
